Different soil types respond differently to water. When it comes to irrigation, application rate must match your soil’s ability to absorb water. High application rates can create surface sealing and runoff, carrying surface soil away. Applying the water at a rate that matches the soil’s needs allows the water to penetrate the soil slowly. Application [...]

When you think about the bottom line of your irrigation system, many questions come to mind. What is the cost to install the system? Where can I save money? When will I see a return on my investment? However, these are just the initial costs. Many people think this is the bottom line and don’t [...]
HYSTERESIS in pressure regulators is the difference in outlet pressures when the inlet pressure is increasing to a certain psi above the regulating pressure, and then decreasing to that same psi. It can vary depending upon the flow and the outlet psi where the measurement is taken. In this chart, look at 40 psi as [...]
Senninger introduced the Wobbler in 1980. The technology of this sprinkler design provides outstanding uniformity at low pressure, making it very popular for water and energy savings. The key to Wobbler technology is the off-center rotary motion and unique groove configuration of the water deflector. The grooves in the deflector divide the flow into numerous [...]
Sprinkler manufacturers do not publish the actual droplet dimensions. This would be difficult to measure and would not address what that size really means. Instead, they provide more general droplet information – small, medium, large. Tighter soils require smaller droplets because they have a lower kinetic energy. However, smaller droplets are susceptible to wind drift, [...]
Low pressure irrigation translates to reduced horsepower requirements and reduced energy consumption. With rising fuel and electricity costs, low operating pressures offer you a tremendous opportunity to lower total pumping costs. The savings vary depending on your specific system. Hours of operation, flow, pressure, energy source, and cost are all considerations. We at Senninger have [...]
A sprinkler profile illustrates where water falls in relation to the sprinkler. This is based on flow, pressure, and height. A denso-gram illustrates the distribution uniformity from this information based on spacing. A single applicator’s uniformity is only part of the picture. The effect of overlapping applicator footprints or, in the case of mechanical move [...]
A pressure regulator limits excess inlet water pressure to a constant outlet pressure. You need constant outlet pressure to ensure that your sprinkler (or emitter) performs well. Water travels through the inlet end of the regulator and around a fixed seat into the critical flow area. The water then enters into a hollow cylinder called [...]
WHAT OUR CUSTOMERS SAY…
“I had been experiencing some real problems with other applicators. The water pattern was poor, causing severe streaking. The i-Wob has really made a difference for me. My dealer was right. It’s reliable and it delivers a real uniform pattern.”- Mike Sabala, Idaho
